Firstly, I am new to allegro and I am not a scripter.
I am using script mentioned below for scrolling worksheet up & down by mouse wheel, but I am facing the problem for vertical scrolling as it stops between the design & dosent allow to scroll downwards. Horizantal scrolling works perfectly.
# use scroll button on mouse to scroll verticallybutton wheel_up "roam y -$roamInc"button wheel_down "roam y $roamInc"
# use shift + scroll button on mouse to scroll horizontallybutton Swheel_up "roam x -$roamInc"button Swheel_down "roam x $roamInc"
Also I can access my worksheet only upto (-128, 161) mm in X direction & (71, -128) mm in Y direction.
How can I increase worksheet size?
Your scroll functions should work fine, mine are the exact same and have no issues, maybe you need an update to your installation?
You can change worksheet size in Setup->Design Parameters->Design
